REVERSIBLE VALVE.

Application filed. September 20, 1923.

To all whom it may concern:

Be it known that I, NILLIAM F. WAGNER, a citizen of the United States, residing at Ambridge, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Reversible Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved reversible valve of the type used in pipe welding or heating furnaces using producer or coke oven gas, the same being commonly referred to in the trade as a butterflyvalve.

Valves of the above type are subjected to intense heat and become overheated to such an extent as to result in warping and twisting of the metal, causing an ineffective seating and leakage of gas. In practice it has been found that such valves must necessarily be removed every two or three weeks for repairs, and they are often damaged to such an extent as to prevent reusing. Hence, considerable expense is attached to the use of this type of valves.

Having observed the defects of valves of the above named type, I aim to substitutea valve therefor which is not open to the objections pointed out, and in carrying out this end, I simply make use of a fluid-cooled valve of novel and improved construction which insures a continuous and proper circulation of the cooling medium to obtain uniform cooling.

Specifically speaking, it is one of the main features of the improved fluid-cooled valve to so construct it as to permit the cooling medium to enter at the center of one side and pass through a separate passage which discharges into the lower end of the interior of the valve, causing the cooling medium to circulate upwardly through the valve to be discharged therefrom through an outlet which leads from the upper end thereof.

Other objects and advantages of the invention will be apparent as the description goes on.

In the accompanying drawings forming a part of this pecification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is an elevation of a two-part valve casing with the furnace intake and Serial No. 663,844.

discharge pipes connected therewith, only fragments of the latter being shown.

Figure 2 is a central vertical section of Fig. 1.

Figure 3 is a central vertical section taken on the line 3-3 of Fig. 2 the valve being shown in elevation.

Figure l is a top plan view of the improved valve removed from its casing.

Figure 5 is a horizontal or longitudinal section through the valve.

Figure 6 is a cross section taken on the line 6-6 of Fig. 4.

In the drawings, the letter C designates a two-part flanged valve casing with which the several pipes (not shown) of the furnace are connected and by means of which the gas is shunted from one to the other side of the furnace in the usual manner. On its interior, the casing C is provided with diagonal inwardly projecting partitions A which form seats for the valve. As is usual, the faces of these seats are so designed as to permit reversal of the valve for shunting the gas from one side of the furnace to the other.

The foregoing details do not constitute a part of the present invention. As before indicated, the novelty of the invention resides in the provision of a reversible watercooled butterfly valve 1 which as is usual, is substantially oval in shape. This valve in its present embodiment, is in the form of a hollow steel casting and it is provided with a marginal or peripheral flange 2 which is adapted to engage the aforesaid seats. It is obvious that the cooling medium is adapted to circulate through the interior of the valve and to permit entrance and escape of this fluid, the valve is provided at 0pposed points with integral tubular eXtensions 3 which constitute journals, these being rotatable in bearings in the valve casing in the usual manner. As seen more clearly in Fig. 6, these extensions 3 communicate with angular passages 4 and 5 respectively on the interior of the casing. The passage 4 constitutes the intake while the remaining passage constitutes the outlet or discharge. As before pointed out, it is very advantageous in a valve of this kind to have the cooling medium enter the casing at its lower end so that it will circulate or flow upwardly to be discharged from the opposite end. To accomplish this result, I make use of a substantially diagonal pipe or conduit 6 which is connected at one end with the passage 4L, being connected at its opposite end to the upper side of the casing and discharging through the latter into the interior of the casing at the lower end thereof. From this point, the water flows upwardly in a substantially uniform sheet and discharges into a similar pipe or con duit 7 which is likewise diagonally disposed and is connected as its upper end to the corresponding end of the casing and con nected at its opposite end with the aforesaid outlet 5. By causing the water to circulate .in this manner, elfective cooling of the valve is insured and all air is exhausted therefrom to overcome possible interference with the circulation. Before completing the description of the valve, attention is directed to the fact that the outer end of the right-hand journal 3 is flat-faced as indicated as -8 and this flat-faced portion projects beyond the casing to permit a lever L to be connected therewith for rotating and reversing the valve in the usual way.

The cooling fluid or medium is supplied to the valve through a pipe F leading from any suitable source and connected at 9 through the medium of a suitable swivel. connection with the fluid intake of the valve. The discharging fluid from the valve escapes through the left-hand journal 3' and passes through the discharge pipe D. A

suitable ,swivel connection. 10 is also arranged between the discharge pipe and the outlet of the valve. Inasmuch as the supply and discharge pipes and swivel connection constitute no part of the invention, they can be of any conventional design and arrangement as is found practical in actual use I When considering the foregoing description in connection with the accompanying drawings, persons skilled in the art to which theinvention relates will no doubt be able to obtain a clear understanding of the same. Hence, a more lengthy description is deemed unnecessary.

Before completing the description, atten tion may be directed to the fact that the valve may be provided in one side or the other with an opening closed by a removable plate 11 to permit access to be had to the interior for cleaning the same.

I claim:

1. A reversible fluid-cooled valve comprising a hollow casting provided at opposed points with fluid intake and discharge passages respectively, said passages being of angular formation and having one end opening through the adjacent edge of the casting with the other end opening throng-hone side face thereof, and a pair of externally disposed conduits arranged in spaced parallelism and connected at their inner ends with said intake and discharge passages and being connected at their outer ends to ports formed in the top wall of the casting at the opposite ends thereof.

2, A reversible fluid-cooled valve comprising a hollow casting which is longitudinally elongated and is provided between its ends at opposed points with fiuid intake and discharge passages respectively, each of said passages being of angular formation and having one end opening through the adjacent edge of the casting-with the op posite end opening through one side face of said casting, said casting being further provided with tubular integral extensions communicating with and: extending from said passages, said extensions constituting journals by means of which the valve is rotatably mounted, and a. pair of external diagonally disposed conduits arranged in substantial parallelism and spaced from each other, said conduits being connected at their inner ends with the top openings of said intake and discharge passages, said casting being provided in its top adjacent its opposite ends with ports with which the outer ends of said conduits are. connected.

In testimony whereof I have hereunto affixed my signature.

WILLIAM F. W -AGNER.
